LIST TAKEN FROM PHONEBUUF. COM..... But I wouldndt say the 4s is superior.... Some reasons why the s3 beats the iphone...
1.NFC capabilities- Not important at all, barely widespread, alot of security issues with current NFC technology
2.DLNA technology- they have this on iOS, its called Qualcomms Skifta
3.MicroSD card slot- one advantage
4.Removable battery- removeable battery phones= phones that freeze more and arent as stable as unibody phones
5.LED notifications- i can just tap my home button to check notifications big deal
6.Bigger 4.8 inch screen- bigger screen size doesnt make it better
7.True HD resolution at 720p- lower PPI and oversaturated colors along with a pentile display makes it worse to view videos and the quality of the video is seriously degraded
8.Widgets- useless, drains battery dramatically on all Android phones
9.Live wallpapers- big deal
10.Wireless toggles- i have this on my iPhone 5
11.Available on all major carriers- so is the iPhone( will be by March)
12.Face unlock-gimmick, you can use someones photo to unlock the phone
13.Lock screen shortcuts-have this already on my jailbroken iPhone
14.SmartStay- gimmick, doesnt even work half the time
15.Pop up play- gimmick, no one ever uses this feature
16.C Pen- S pen doesnt work on the S3
17.Best shot- doesnt matter, still takes worse photos then the 4S/5
18.Data usage controls-iOS can already monitor how much data you use
19.Battery statistics- battery statistics on iOS aswell
20.True multitasking- gimmick, drains alot more batttery then iOS's way of multitasking
21.Adobe Flash- no more flash on Android, plus i can get flash on my iPhone
22.Multiple app stores- multiple third party stores with plenty of viruses and malware ready to take over your phone and steal all your information
23.More e-mail attachment options- okay advantage here
24.More in-app sharing options- not much of a difference of what i can do on my jailbroken iPhone
25.Google Maps and Street View- Google employees admit the iOS version is better then the Android version
26.File explorers, works like USB flash drive- have this already on my jailbroken iPhone
27.Haptic feedback- have this already on my jailbroken iPhone
28.Voice controls (different from voice assistants)- voice assistants are better then voice controls
29.Driving mode- shouldnt really be using your phone while your driving anyway
30.Browsing options (desktop, offline reading, incognito)- iOS has had this for a long time now
31.T9 dialing-not sure
32.Wireless app management-same thing on iOS
33.Better app integration- iOS has a much better ecosystem then Android, this is moot
34.Power saving- what difference does it make if it makes your phone slow down to a crawl, iOS has plenty built in power saving features
35.App refund policy-iOS has this aswell
36.Hide or disable any app- i can do this on my jailbroken iPhone
37.Reject list- i have this on my jailbroken iPhone
38.Direct call-no difference to just tap call
39.Double tap to top- doesnt work good at all, is a straight up gimmick, doesnt compare to tap to top on iOS
40.Smart alert- gimmick and doesnt work half the time
41.Tilt to zoom- gimmick
42.Pan to move-gimmick
43.Turn over to mute- i have this on my jailbroken iphone
44.Easier screenshots- swiping with your hand (which doesnt work half the time) isnt better then the lock/ home button press on iOS
45.Custom launchers- custom launchers that hog your battery life and is incompatible with alot of Android phones
46.Custom lock screens- have this on my jailbroken iPhone
47.Third party keyboards- useless, iOS has one of the best keyboards in the industry hands down
48.Universal microUSB charging port- lightning cable is reversible and allows for better connections in a car
49.USB host (for USB connections)- not sure about this
50.Share shot and buddy photo share- i have the same features on my jailbroken iPhone
BOTH ARE GREAT DEVICES BUT THIS LIST CAN GO ON AND ON
